Avon catchment

Earthquake damage to land and infrastructure alongside the Avon River has led to an increase in the severity of flooding to existing flood-prone land and to some new areas.

This has also had an adverse effect on land zoning, existing flood mitigation infrastructure, stormwater systems, critical roads as well as other services.

The Avon River Flood Protection Programme (FPP) is investigating options for flood management of stopbanks, pumping and other measures to restore flood risk to pre-earthquake levels. Future use of the residential red zone impacts on flood management options.
